Hold the lucet in your left hand so that the tines of the fork point away from your hand and you can see its ‘u’ shape with the hole below. Take the string/wool/twine that you are going to use, you will need quite a lot, and it will help to place it on your right hand side.

Place the end length of the thread between the fork so that the cut end is towards you. Pull this cut end, wrapping it around the right tine of the lucet and thread it through the hole from behind, pull through enough that you can trap the end with the hand that is holding the lucet.

Get the main length of thread from behind the left tine and wrap it forwards around the tine, then pull it to the right, taut across the front of both tines. The right hand tine will already have the loop you made a moment ago. Try and keep the thread reasonably taut while you lift the old loop up over the new taught thread, and slip it over the tip of the tine.

Following the thread, turn the lucet around, so that you are now looking at what was the back. Still keeping the thread taut, again pull it to the right across both tines above the existing loop on the right hand tine. Pick up that old loop, lift it over the taut thread and slip it over the tip of the tine. All you need to do now is continue this process; turn the lucet, wrap the thread, slip off the loop, until you have a cord long enough.
